Two news article tags/categories for AT&T?
Why are there two news article tags/categories named "AT&T"?
There seems to be no rhyme or reason to which articles get which tag(s). Some get only one, some get only the other, and some get both.
Just guessing here.
Maybe those were once "SBC" and "AT&T", but corporate mergers happened.
If that's true, then one of them should be marked as deprecated and should no longer be used. Instead, recent stories are tagged with one, the other, or both.
